Review on Standard Motor Products B22001 Tool by George Saunier

Drill is annoying. The socket drive tool is what you need here. I drilled the hole in the EGR manifold with another good bit, similar but slightly smaller than this bit from the kit. This extra step removes most of the material that needs to be drilled out first. The drill from this set has very poor cutting ability. If you have calipers, you can be sure that you are using the right size overall. After pre-drilling the hole with a slightly smaller drill bit, I used the included drill bit to finish the necessary drilling. From then on everything went perfectly.
